What material are these pistons made from and why is it important?

These pistons are forged from 2618 aluminum. This material is chosen for its high tensile strength, which is essential for handling the extreme pressures and temperatures found in high-demand performance engines.

What is the Forged Side Relief (FSR) design?

The FSR design is a proprietary JE Pistons feature that helps minimize friction and power loss. It achieves this through a reduced skirt width and a shorter wrist pin, which also contributes to saving weight on the rotating assembly.

Are any special tools or components needed for installation?

Installation of performance pistons typically requires specialized knowledge and tools. It is recommended to consult the manufacturer's installation instructions and consider professional installation for optimal results.

Product Details

If you're building a high-performance big block Chevrolet (BBC) engine, a solid set of pistons is crucial for handling the stress and delivering power. This set of eight dome pistons from JE Pistons is forged in the USA from 2618 aluminum, a material chosen for its high tensile strength, making it well-suited for demanding performance applications where durability is key.

JE Pistons brings over 75 years of experience to their forged piston designs, and these are no exception. They feature a proprietary Forged Side Relief (FSR) forging design, which helps reduce friction and power loss by using a narrower skirt and a shorter wrist pin, also saving weight. Depending on the specific application, these pistons may also include an accumulator groove to help manage combustion gas pressure, leading to better ring seal and consistent power delivery. Some applications also benefit from a skirt coating that further reduces friction and wear on the piston skirts and cylinder walls, while also contributing to quieter operation.

These pistons are designed specifically for each engine and use application, ensuring optimized performance and durability. The kit includes all eight pistons, ready for your engine build. Please note that these pistons are not CARB approved and cannot be shipped to California.
